Connection Method of Carbon Steel Seamless Pipe

(1) The importance of heavy industrial structures, large-span structures, high-rise or super-high-rise civil building structures or other important structural structures, should consider the selection of high-quality seamless steel pipes, generally according to the working nature of industrial and civil buildings, you can choose ordinary quality Seamless steel pipe.

(2) Under the direct load of dynamic load structure and strong earthquake zone structure, the comprehensive performance of seamless steel pipe should be selected; usually, the structure of static load can choose the seamless steel pipe with lower price.

(3) The welding method may cause welding deformation, welding stress and other welding defects during the welding process, and there is a risk of cracking or brittle fracture, so the material requirements for the welding structure should be strict.

(4) The influence of structural temperature and environment, seamless steel tubes are easy to be cold and brittle at low temperature, so the structure under low temperature conditions, especially the welded structure, should choose the performance of stabilizing steel with good resistance to low temperature brittleness.
